• Specially designed gas enterance can prevent oil flowing back,separated tank, separated devices at the exhaust port, avoiding oil-spraying and reduse pollution. Constructed with alloy aluminium casing, it has high heat- scattering efficiency, which can keep the pump running normally, long-lasting. and better outer-figure quality. The electric machinery and the pump are wholly designed and direct drive, which makes the product more compact, lighter and more rational. An elastomeric coupling results in extremely quiet, smooth-running operation. Equiped with design of great starting moment is easy for starting and high in efficiency, which can keep it running normally even in lower temperature environment and lower volt. Incorporated the lubrication system designed to provide clean, filtered oil to all internal bearings and wear surface, regardless of the pump operateing pressure. Cleaner oil means reduced maintenance and lower operating costs.
